Abstract
The invention relates to a dust separation device for improving the separation efficiency of a dust collector. The dust separation device comprises a separation container, wherein a mesh filter is arranged in an inner cavity of the separation container, a secondary cyclone unit is arranged in the central position of the inner cavity of the separation container, a plurality of guide blades which are distributed in an annular way are additionally arranged between the mesh filter and the secondary cyclone unit, each guide blade is connected with the mesh filter through a corresponding segmenting sheet, and an airflow passage is arranged between the secondary cyclone unit and the mesh filter; and the segmenting sheet is arranged in a tangential air inlet position of the secondary cyclone unit. The dust separation device has the beneficial effects that the airflow entering a tangential air inlet is circumferentially cut, so that the turbulence of the airflow can be reduced, the pressure in a dust cup can be uniformly distributed, the airflow uniformly and stably enters the secondary cyclone unit, the separation efficiency of the system is increased, and the pressure loss caused by the airflow turbulence can be reduced.
Description
Technical field
The present invention relates to the dust catcher technology, relate in particular to a kind of for the dust-separating appliance that improves the dust catcher separative efficiency.
Background technology
The dust catcher of existing a lot of whirlwind modes, its mode of operation is after sucking the air that is mixed with dust the air that is mixed with dust to be rotated at a high speed, centrifugal force by rotary air then, from the air that is mixed with dirt with dust or little dirt with after heavily throw away one by one to light order, the dust that throws away or little dirt are trapped in the dirt bucket.But in Cyclonic dust collector, especially the cup type structure of the dirt of multistage cyclone, the outer mesh filter of original adoption, the downstream of mesh filter has several air-flows to enter the tangent air inlet of its downstream second stage whirlwind outside, and dust-contained airflow enters tangent air inlet after entering the initial separator separation, because the pressure distribution inequality in the dirt cup, turbulent flow appears in air-flow in the dirt cup, cause influencing separative efficiency, increases the pressure loss.Therefore, in conjunction with above aspect, need reasonably improve prior art.
Summary of the invention
At above defective, the invention provides and a kind ofly be conducive to reduce turbulent air flow, improve system's separative efficiency, significantly reduce the dust-separating appliance that is used for improving the dust catcher separative efficiency of pressure loss, to solve many deficiencies of prior art.
For achieving the above object, the present invention is by the following technical solutions:
A kind of for the dust-separating appliance that improves the dust catcher separative efficiency, comprise separation container, be provided with mesh filter in this separation container inner chamber, be positioned at separation container lumen centers position and be provided with second level cyclone unit, between described second level cyclone unit and the mesh filter gas channel is set; Simultaneously, each guide vane joins by cutting plate and the mesh filter of correspondence.
Described cutting plate is arranged at the place, tangential air intake entry position of second level cyclone unit, be provided with the central gas stream passage in the cyclone unit of the described second level, and the air-flow of the gas channel between second level cyclone unit and the mesh filter separates the back through second level cyclone unit and flows out from the central gas circulation road;
Divided of described gas channel is cut into several autonomous channels.
Beneficial effect for the dust-separating appliance that improves the dust catcher separative efficiency of the present invention is: set up a cutting plate by the tangential air intake porch in second level cyclone unit, the air-flow that enters tangent air inlet is circumferentially cut, like this when reducing turbulent air flow, make the pressure distribution in the dirt cup even, air-flow is uniform and stable enters second level cyclone unit, thereby improved the separative efficiency of system, reduced the pressure loss that brings because of air turbulence.
Description of drawings
With reference to the accompanying drawings the present invention is described in further detail below.
Fig. 1 is the profile of the described dust-separating appliance of the embodiment of the invention;
Fig. 2 is that the embodiment of the invention is described for the outside schematic diagram of the dust-separating appliance that improves the dust catcher separative efficiency.
Among the figure:
1, external air inlet mouth; 2, guide vane; 3, separation container; 4, dust-collecting cavity; 5, mesh filter; 6, cutting plate; 7, gas channel; 8, central gas stream passage; 9, second level cyclone unit.
The specific embodiment
Shown in Fig. 1-2, the embodiment of the invention is described for the dust-separating appliance that improves the dust catcher separative efficiency, comprise separation container 3, offer external air inlet mouth 1 on the described separation container 3, be provided with mesh filter 5 in these separation container 3 inner chambers and this filter end stretches in the dust-collecting cavity 4; Simultaneously, be positioned at separation container 3 lumen centers positions and be provided with second level cyclone unit 9, these second level cyclone unit 9 tops arrange central gas stream passage 8; Worth emphasis is pointed out that, set up the guide vane 2 of some annular spread between described mesh filter 5 and the second level cyclone unit 9, simultaneously, the tangential air intake porch that is positioned at second level cyclone unit 9 is set up cutting plate 6 and each guide vane 2 cutting plate 6 by correspondence and is joined with mesh filter 5, between per two adjacent guide vanes 2 gas channel 7 is set, thereby the air-flow that will enter tangent air inlet cuts circumferentially.
The above embodiment of the invention is described for the dust-separating appliance that improves the dust catcher separative efficiency, during work, set up a cutting plate 6 by the tangential air intake porch in second level cyclone unit 9, the air-flow that enters tangent air inlet is circumferentially cut, when reducing turbulent air flow, make the pressure distribution in the dirt cup even like this, air-flow is uniform and stable enters second level cyclone unit 9, thereby improved the separative efficiency of system, reduced the pressure loss that brings because of air turbulence.
Above embodiment is the more preferably specific embodiment a kind of of the present invention, the common variation that those skilled in the art carry out in the technical program scope and replace and should be included in protection scope of the present invention.
